Supply and Exchange Agreements [Abstract]
Supply and Exchange Agreements	Supply and Exchange Agreements HIE entered into several agreements with Barclays Bank PLC ("Barclays"), referred to collectively as the Supply and Exchange Agreements, on September 25, 2013 in connection with the acquisition of HIE. HIE entered into the Supply and Exchange Agreements for the purpose of managing our working capital and the crude oil and refined product inventory at the refinery. Pursuant to the Supply and Exchange Agreements, Barclays holds title to all of the crude oil in the tanks at the refinery and holds title to a majority of our refined product inventory in our tanks at the refinery. Barclays also prepaid us for certain inventory held at locations outside of our refinery. We hold title to the inventory during the refining process. Barclays sells the crude oil as it is discharged out of the refinery's tanks. We exchange refined product owned by Barclays stored in our tanks for equal volumes of refined product produced by our refinery when we execute third party sales of refined product. We currently market and sell the refined product independently to third parties. The Supply and Exchange Agreements have an initial term of three years with two one-year renewal options. We record the inventory owned by Barclays on our behalf because we maintain the risk of loss until the refined products are sold to third parties. Because we do not hold legal title to the crude oil inventory until it enters the refinery, we record a liability in an amount equal to the carrying value of the crude oil inventory. In accordance with the terms of the Supply and Exchange Agreements, the volume of refined products purchased by Barclays in connection with the acquisition of HIE is known as the “Block Volume”. To the extent we have refined products inventory volumes at period-end in excess of the Block Volume, we only record a liability for the Block Volume valued at the per barrel carrying value of the refined product inventory owned by Barclays. From time to time, we may sell refined product inventory that causes our refined product inventory to be less than the Block Volume. To the extent of this shortfall, we record a liability for the volumes that we would need to purchase at current market prices in order to meet the Block Volume requirement. The liability related to the Supply and Exchange Agreements is included in Obligations under supply and exchange agreements on our unaudited consolidated balance sheet. For the three months ended March 31, 2014, we incurred approximately $3.5 million in handling fees related to the Supply and Exchange Agreements, which is included in Cost of revenues on our unaudited condensed consolidated statements of operations. For the three months ended March 31, 2014, Interest expense and financing costs, net, on our unaudited condensed consolidated statements of operations includes $1.4 million of expenses related to the Supply and Exchange Agreements.
